Integrate in-memory debug-info dumps into the `--orc-lazy-debug`
command-line option instead of exposing built-in functions to be called
from JITed code. This reduces overall amount of code (removing
`ExecutionUtils.cpp`) and seems cleaner anyway.
All existing items of `OrcDumpKind` work on IR level and run in the
IR-transform step of the JIT. The newly added `DumpDebugDescriptor` and
`DumpDebugObjects` must run after debug-registration and thus are
deferred to the Object-transform step of the JIT. This separation is the
major side-effect of the patch.
The original commit 263efb044add93b9 was reverted in #79055, because
the gcc 7.5 bot had found a missing std::move().
Reverts llvm/llvm-project#76822
This fails to build with gcc 7.5:
```
llvm/tools/lli/lli.cpp:1087:16: error: could not convert ‘Obj’ from ‘std::unique_ptr<llvm::MemoryBuffer>’ to ‘llvm::Expected<std::unique_ptr<llvm::MemoryBuffer> >’
return Obj;
